Description of the embodiments

The following detailed description of the utility model refers to the accompanying drawings, which illustrate specific embodiments of the utility model:

as shown in the figure, the anti-collision connecting plate device of the lifter consists of a connecting plate 1 and a connecting rod mechanism. The connecting plate 1 has a width slightly smaller than the width of the cabinet 2 of the elevator and is located inside the outlet of the cabinet 2 of the elevator. The bottom of the connecting plate 1 is hinged to the floor of the case 2 of the elevator, so that the connecting plate 1 can be vertically received in the case 2 or horizontally placed when rotating, and the floor 3 of the case 2 and the floor are connected, so that gaps and height differences between the elevator and the floor are made up, and smooth transition between the elevator and the floor can be realized. The connecting rod mechanism is used for the retracting operation of the connecting plate.

In order to ensure the strength, the connecting plate 1 is made of steel plates in a hinged manner: the two sides of the bottom of the connecting plate 1 are respectively welded with a short shaft, the side walls of the two sides are welded with a rotary support 4 in the case, and the rotary connection is realized through the cooperation of the short shafts and the rotary support 4. The rotary support 4 is fixedly arranged on the floor of the chassis through bolts, and the rotary support 4 is provided with a shaft hole matched with the short shaft.

The link mechanism consists of a link 5 and a retraction structure. One end of the connecting rod 5 is hinged to one side of the connecting plate 1, and the other end of the connecting rod 5 is hinged to the folding and unfolding structure, and the folding and unfolding structure drives the connecting plate to rotate through the connecting rod, so that folding and unfolding are realized. The retractable structure consists of an outer cylinder 6 and an inner cylinder 7 which are vertically arranged, the outer cylinder 6 is fixedly arranged on the ground of the case 2 through a bottom plate at the bottom, and the inner cylinder 7 vertically slides in the outer cylinder 6. The inner cylinder 7 is fixedly provided with a horizontal slide bar 8 which is arranged on the inner cylinder 7 in a threaded connection mode. The lateral wall of urceolus 6 is equipped with vertical spout 9, and slide bar 8 one end stretches out the spout 9 outside and articulated with connecting rod 5, and when the relative urceolus 6 of inner tube 7 was slided, spout 9 was spacing to slide bar 8, and inner tube 7 realized receiving through connecting rod 5 pulling connecting plate 1.

In order to facilitate the sliding operation of the inner cylinder 7, a handle 10 is fixedly installed on the inner cylinder 7, a corresponding handle chute 11 is arranged at a corresponding position of the outer cylinder 6, the handle 10 extends out of the outer cylinder 6, and the inner cylinder 7 can be pulled to slide relatively in the outer cylinder 6 through the handle 10.

Because the connecting plate 1 has two states of being completely folded and completely placed in the using process, the two states are limited, so that the normal use of the connecting plate can be ensured and the lifting of the lifter is not influenced. The travel of the handle 10 and the slide bar 8 can be limited partially through the slide groove, and when the inner cylinder 7 moves to the upper travel position and the connecting plate 1 is retracted, the limiting mode is as follows: the support 12 is welded on one side of the top end of the handle chute 11, the support 12 is welded on the side wall of the outer cylinder 6, the handle 10 is designed into a folding structure, namely, the extending end of the handle 10 is connected with a folding section, the folding section can be horizontally folded through the structure of the rotating shaft, and the folding section is matched with the support 12 and supported on the top surface of the support 12, so that the inner cylinder 7 is kept at the upper stroke limit position. The arc grooves matched with the folding sections are arranged on the support 12, so that misoperation caused by sliding of the handle 10 is avoided. The bottom of the inner cylinder 7 is provided with a bracket 13, the bracket consists of a bottom base and a supporting rod between the base and the bottom surface of the inner cylinder, and when the inner cylinder 7 moves to the lower stroke limit position, the base of the bracket 13 contacts with the bottom surface of the outer cylinder 6 to limit the continuous sliding of the inner cylinder.

When the inner cylinder 7 slides to the upper stroke end position, the connecting plate 1 is vertically retracted, the handle 10 is folded and supported to the support 12, the vertical state of the connecting plate 1 is maintained, and at the moment, the lifter can be lifted and operated. When the inner cylinder 7 slides down to the down stroke position, the bracket 13 contacts the inner bottom surface of the outer cylinder 6, the connecting plate 1 is placed horizontally, and at this time, the in-out transportation operation of the lifter can be performed.
